Even though squirrels may look cute and fluffy, they tend to wreak havoc in your home. The best way to prevent these messy rodents from making themselves at home on your property is to take all the necessary steps to keep them out.

Below, I’ve singled out 5 excellent squirrel poison products, making emphasis on their major characteristic features. You’re welcome to research each of them further and choose the best squirrel killer for your needs.

1. JT Eaton Blocks: Excellent Squirrel Bait Poison – Top Pick


  • Active Ingredient: Diphacinone 0.005%
  • Number of Items: 144
  • Item Weight: 1 ounces
  • Item Dimensions LxWxH: 11 x 11 x 10 inches
  • Target Species: Rats and Mice

This squirrel killer comes in a 9-lb bucket and has peanut butter-tasting chunks in it. Squirrels and other rodents love chowing down on these babies non-stop. You will have to be patient with these bait blocks, though, for it may take up to a couple of weeks to start seeing positive dynamics.

Your squirrel home invaders will munch on this poison, go away, then come back again and again for a few more doses that will eventually turn out to be lethal.

The JT Eaton blocks are bright green, which means your kids won’t accidentally confuse them for food. However, make sure you keep this poison out of reach of your kids and domestic animals. The poison inside the bucket isn’t the most potent on the scene due to the state regulations, however, these bait blocks pose a health threat to your dear ones anyway.

Don’t forget to refresh your supply of this poison once it’s used up. So if you have a squirrel problem or any other rodent infestation, try this squirrel killing solution. This might be exactly what you need.

As a matter of fact, this is one of the go-to products for rodent control approved by our local rodent exterminators. Yep, squirrels, mice, and rats love it to death — literally.

Contrac Blox Rodent Control: Professional Squirrel Killer

This rodenticide is easy to handle. Don’t forget that although Contrac Blox is highly effective, it’s also dangerous for pets and kids. So make sure you get the locking bait stations to prevent your family members from getting poisoned. And remember to wear your work gloves when working with this solution to protect your skin.

This product is considered to be among the best squirrel baits, so if you decide to do your own pest control, you should definitely try it out. Chances are high that it will solve your rodent problem and prevent a recurrence.

Aside from squirrels, Tomcat will also help you clean other unwanted pesky visitors out of your property, such as chipmunks and mice.

This poison works well both inside and outside your property. And it’s weather-resistant. If squirrels are doing a lot of damage to your garden or attic, perhaps, it’s time to take things into your own hands when it comes to squirrel control.

It has proven to work effectively both inside and outside your property, in private homes and industrial environments. Since this squirrel poison comes in an 18-lb bucket, you can use lots of it on your property (with some sense of measure in mind, of course).

I recommend using this poison with bait boxes only. Make sure you study its label prior to using the Final Blox Squirrel bait. Each state in the U.S. has different rules in terms of rodenticide usage. You should be aware of them in order to follow them.

Buyer’s Guide

How to Poison Squirrels in the Most Effective Way?

Choosing the best poison is the key to eradicating your squirrel problem. If squirrels have invaded your garden, make sure you opt for the baits and poison options that are water-resistant. Otherwise, they may dissolve in the rain without delivering the desired effect.

Once you stick with the right product for your needs, don’t forget that all squirrel poisons contain chemicals that are dangerous to use around your cats, dogs, and little family members.

How to Use Squirrel Poison and Baits?

Always wear your work gloves when handling squirrel poisons and baits. Apply poison products only where you’ve noticed squirrel activity. If you’re using a one-bite bait, then poisoning squirrels in your yard or your attic will only take a few days.

With weaker poisons, you’re going to wait longer. In either case, always study the product label prior to using any squirrel poison solution. The label covers such issues as application methods, storage specifics, and disposal instructions.

And don’t forget to walk on the safe side in terms of how the state where you live regulates poisoning squirrels, for each state has its own ground squirrel management guidelines.

What Are the Main Squirrel Poison Types?


There are two main squirrel poison types: single (one-bite) feed and multiple feed. Just like their names suggest, they refer to a certain number of times a pesky fluffy animal has to munch on the poisonous ‘dessert’ for it to work.

The single feed poison baits require only a few bites to deliver great results, while the multiple feed poison baits mean it’s going to take more than just one feeding for the pesky invaders to leave this world (and, most importantly, leave your home alone!) due to the poison effects.

What About the Safety Measures?

Squirrels spread health hazards, contaminate food, and damage your home. Therefore, effective squirrel control is paramount. However, you should always remember that rodenticides are toxic and understand the risks of using these poisons around kids and pets.

The best way to reduce the risks of getting your loved ones poisoned is by following each individual poison product label. The label has all the necessary details on product application and use. Some squirrel poisons, for example, can be used with bait stations — handy devices that prevent domestic animals and your little family members from accessing the poison.



Will Squirrels Eat Rat Poison?

Just like rat traps can kill squirrels (with slight modifications implemented), many rat poisons work well on squirrels as well. However, if you want to eliminate squirrels in the most effective way possible, purchasing the type of poison that’s made precisely to deal with squirrels would be the best option. Fortunately, you’ll be spoilt for choice when it comes to a wide variety of rodent killers available on the market.

How Fast Will Rat Poison Kill a Squirrel?

It depends on the type of squirrel poison you’ll stay with. In my squirrel poison reviews, I’ve touched upon this issue, so you’re free to choose what suits you best: single feed (and highly toxic) poisons or multiple feed (and less chemical-stuffed) options. Now that you know the pros and cons, the choice is exceptionally easy to make.

Where to Put Squirrel Poison?

Never forget that squirrel poisons are very hazardous to more than just squirrels. Your pet can easily eat the thing and get lethally poisoned. Therefore, make sure you use the squirrel poison in an area that’s accessible to the squirrel, and only to the squirrel.

Typically, homeowners hide squirrel poisons in trees, along their rooftops, or near their attics. These places are frequently visited by squirrels, so they will definitely come back and taste the ‘yummies’ you’ve prepared for them.

How to Get Squirrels to Eat Poison?

The importance of purchasing poison that’s made expressly for squirrels cannot be underestimated. The thing is, squirrel pesticides contain ingredients that attract only these cute-but-destructive rodents. These ingredients are peanut butter, nuts, and sweetened nut products.

Therefore, if you’re on the hunt for the most effective squirrel killing solution, make sure the product you’ll ultimately stick with has a flavor of seeds or nuts.
